A tether of super-strong material linking a position on the surface of a planet with a point in geosynchronous orbit above that position in space.

Allowing a 'lift' or 'elevator' to be run from ground level to orbit.

The invention/discovery of thruster plate technology for orbital shuttles makes this means of orbital transport uneconomical. So few worlds built such an engineering feat before discovering thruster plates.

Terra (1827 Solomani Rim) is one such world where the Beanstalk was already under construction when thruster plates were discovered.
